iw dev returns Device or resource busy

I'm trying to follow this manual in order to setup an accesspoint on my machine. What can I do in order to fix that busy issue?

   

iw dev wlan0 interface add wlan0_sta type managed addr 12:34:56:78:ab:cd

    command failed: Device or resource busy (-16)

$ iw list

Excerpt:

    Wiphy phy0
    ...
            valid interface combinations:
                     * #{ managed } <= 1, #{ P2P-device } <= 1, #{ P2P-client, P2P-GO } <= 1,
                       total <= 3, #channels <= 2
                     * #{ managed } <= 1, #{ AP } <= 1, #{ P2P-client } <= 1, #{ P2P-device } <= 1,
                       total <= 4, #channels <= 1

So far I tried:     

ifconfig wlan0 down

and

ip link set dev wlan0 down

and 

service wpa_supplicant stop
